Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00428 | $0.03559 |
| Opus 5 | $0.00214 | $0.01780 |
| Sonnet 5 | $0.00086 | $0.00712 |
| Haiku 4.5 | $0.00043 | $0.00356 |
Grade A, and why
appendix-ai-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Appendix E - AI Agents on the CLI
Overview
AI CLI Agents represent a new class of tools that transform the developer's terminal from a command executor into an intelligent, collaborative workspace. These agents understand natural language, maintain context about entire codebases, and perform complex multi-step development tasks autonomously — from architectural refactoring to test generation to documentation.
The command-line interface is an ideal environment for AI agents: text-based, sandboxed, and structured. Unlike GUI agents that must interpret visual layouts, CLI agents work directly with code, files, and system commands, enabling precise and auditable automation.
Core Principle: Choose the CLI agent based on your workflow: Claude Code for architectural work, Gemini CLI for multimodal and cloud tasks, Aider for git-centric TDD, GitHub Copilot CLI for GitHub-integrated workflows.
When This Skill Applies
Activate this pattern when:
- Performing large-scale refactoring across many files
- Generating comprehensive test suites for existing code
- Generating or updating technical documentation
- Implementing features described in natural language
- Integrating with CI/CD pipelines for automated code review
- Comparing AI CLI tools for a team's development workflow
- Setting up CLAUDE.md / GEMINI.md project memory files
CLI Agent Comparison
| Agent | Provider | Core Strength | Best For |
|---|---|---|---|
| Claude Code | Anthropic | Deep codebase understanding, architectural reasoning | Large-scale refactoring, multi-file changes, architectural tasks |
| Gemini CLI | Open-source, multimodal, large context window, Google Cloud integration | Multimodal tasks, Google Cloud workflows, broad accessibility | |
| Aider | Open Source | Git-centric, auto-commit, TDD workflow, model-agnostic | Test-driven development, precise bug fixes, auditable changes |
| GitHub Copilot CLI | GitHub/Microsoft | Deep GitHub ecosystem integration, issue→PR workflow | GitHub-integrated teams, automated issue resolution |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

appendix-ai-cli is a skill published in the GitHub repository hajekim/agentic-design-patterns-skills (4 stars, last pushed 5mo ago), licensed MIT. It adds 428 tokens to every session and 3,559 once invoked, about $0.0021 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

onboard-repo
Index an unfamiliar codebase into the knowledge graph, then produce a first orientation map -- entry points, most-depended-upon modules, hotspots, test topology.
impact-audit
Blast radius of a change you have not made yet -- traces a symbol across federated repositories, splits impact per repo, and reports what must ship together.
review-pr
Review a PR or branch diff using the knowledge graph for full structural context. Outputs a structured review with blast-radius analysis.
build-graph
Build or update the code review knowledge graph. Run this first to initialize, or let hooks keep it updated automatically.

Analyze raw prompts, identify intent and gaps, match ECC components (skills/commands/agents/hooks), and output a ready-to-paste optimized prompt. Advisory role only — never executes the task itself.
